Plate Yield at 68% target nesting yield: a worked example
This worked example runs the plate yield numbers for a tougher week than the baseline: 68% target nesting yield instead of the typical 95%. Plate Yield is the share of purchased steel plate that ends up in finished shell courses, heads, and nozzles rather than in the drop bin.
The inputs for this scenario
- Off-cut or scrapped plate area: 8 units (held at the documented default)
- Gross plate area purchased: 250 units (held at the documented default)
- Target nesting yield: 68 % (the input this scenario stresses; the baseline uses 95)
Working through the calculation
- The calculation starts from the formula this tool documents: Plate Yield rate = affected amount รท total amount.
- Rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
- Gap to target works out to 64.8 points at these inputs.
- Affected count works out to 8 count at these inputs.
- Total count works out to 250 count at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where target nesting yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
- Use it after a nest is programmed or at month-end when reconciling plate purchases against parts shipped for a vessel or tank job. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
Results at a glance
- Rate: 3.2 % (headline result)
